MILLENNIUM PARK — Chicago’s showcase park has been packed full of free music this year.

On Monday evening, Afro pop stars Amadou and Miriam will play the summer concert series formerly known as Downtown Sound Monday night at Millennium Park’s Jay Pritzker Pavilion, 201 E. Randolph St.

A blind married couple from Mali who met as children, the duo began as a blues-based duo in the mid-1980’s. They incorporate Western pop influences into their sound, and have opened shows for U2 and Coldplay. They’ve been described as “eminently danceable.”

The Washington Post says the pair create “rich sonic tapestries that are intensely joyful while retaining the muted cool of indie rock.”

“The 2017 lineup includes artists from the U.S. as well as Canada, Colombia, Cuba, Mali, Mexico and Senegal — advancing Chicago’s status as a welcoming city,” the city’s Department of Cultural Affairs and Special Events said in a statement.

All shows are free and will start at 6:30 p.m. rain or shine. The headliner for Monday, Aug. 21 has yet to be announced. Here is the full lineup:
